如何重用Get-VMMServer连接？

我正在编写一个 C# 应用程序，其 Main() 将启动多个线程，每个线程都会触发 Get-VM commandlet。我为此使用 RunspacePool。

目前，每个线程必须首先触发 Get-VMMServer，然后触发 Get-VM。 Get-VMMServer 大约需要 5-6 秒，从而显着影响性能。下面是代码片段：

    static void Main()
    {
        InitialSessionState iss = InitialSessionState.CreateDefault();
        PSSnapInException warning;

        iss.ImportPSSnapIn("Microsoft.SystemCenter.VirtualMachineManager", out warning);

        RunspacePool rsp = RunspaceFactory.CreateRunspacePool(iss);
        rsp.Open();


        using (rsp)
        {
            ClassTest n = new ClassTest();
            n.intializeConnection(rsp);

            Thread t1 = new Thread(new ThreadStart(n.RunScript));
            t1.Start();

            Thread t2 = new Thread(new ThreadStart(n.RunScript));
            t2.Start();
            ....
        }
        ....
    }

    class ClassTest
    {
        RunspacePool rsp;

        public void intializeConnection(RunspacePool _rsp)
        {
            rsp = _rsp;
        }

        public void RunScript()
        {
            PowerShell ps = PowerShell.Create();

            ps.RunspacePool = rsp;
            ps.AddCommand("Get-VMMServer") AddParameter(...); // Doing this in every thread.

            ps.AddCommand("Get-VM").AddParameter("Get-VM", "someVM");

            StringBuilder stringBuilder = new StringBuilder();

            foreach (PSObject result in ps.Invoke())
            {
                ...
            }
        }
    }

Get-VMMServer 连接到 Virtual Machine Manager 服务器（如果连接尚不存在），并从 Virtual Machine Manager 数据库中检索表示该服务器的对象。

我希望每个线程都能重用此连接。

我怎样才能实现这个目标？有没有办法在 Main() 中创建此连接，以便池中的所有运行空间都可以使用它？

I am writing a C# application whose Main() will start multiple threads, each thread firing Get-VM commandlet. I am using RunspacePool for this.

Currently each thread has to first fire Get-VMMServer and then Get-VM. Get-VMMServer takes around 5-6 seconds giving a significant performance hit. Below is the code snippet:

    static void Main()
    {
        InitialSessionState iss = InitialSessionState.CreateDefault();
        PSSnapInException warning;

        iss.ImportPSSnapIn("Microsoft.SystemCenter.VirtualMachineManager", out warning);

        RunspacePool rsp = RunspaceFactory.CreateRunspacePool(iss);
        rsp.Open();


        using (rsp)
        {
            ClassTest n = new ClassTest();
            n.intializeConnection(rsp);

            Thread t1 = new Thread(new ThreadStart(n.RunScript));
            t1.Start();

            Thread t2 = new Thread(new ThreadStart(n.RunScript));
            t2.Start();
            ....
        }
        ....
    }

    class ClassTest
    {
        RunspacePool rsp;

        public void intializeConnection(RunspacePool _rsp)
        {
            rsp = _rsp;
        }

        public void RunScript()
        {
            PowerShell ps = PowerShell.Create();

            ps.RunspacePool = rsp;
            ps.AddCommand("Get-VMMServer") AddParameter(...); // Doing this in every thread.

            ps.AddCommand("Get-VM").AddParameter("Get-VM", "someVM");

            StringBuilder stringBuilder = new StringBuilder();

            foreach (PSObject result in ps.Invoke())
            {
                ...
            }
        }
    }

Get-VMMServer connects to a Virtual Machine Manager server (if a connection does not already exist) and retrieves the object that represents this server from the Virtual Machine Manager database.

I want this connection to be reused by each threads.

How can I achieve this? Is there a way to create this connection already in the Main() so that all the Runspaces in the pool can use it?
